Given numbers are 638, 626, 189, 926
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 626) = 199694
GCD(638, 626) = ( 638 x 626 ) / 199694
= 638 / 626
= 638
Step2:
LCM(2, 189) = 378
GCD(2, 189) = ( 2 x 189 ) / 378
= 2 / 189
= 2
Step3:
LCM(1, 926) = 926
GCD(1, 926) = ( 1 x 926 ) / 926
= 1 / 926
= 1
So, Greatest Common Divisor of 638, 626, 189, 926 is 1
